Abstract: The present invention provides wood preservative compositions comprising micronized particles. In one embodiment, the composition comprises dispersions of micronized metal or metal compounds. In another embodiment, the wood preservative composition comprises an inorganic component comprising a metal or metal compound and organic biocide. When the composition comprises an inorganic component and an organic biocide, the inorganic component or the organic biocide or both are present as micronized particles. When compositions of the present invention are used for preservation of wood, there is minimal leaching of the metal and biocide from the wood.

Abstract: A wood preservative includes injectable particles comprising one or more sparingly soluble copper salts. The copper-based particles are sufficiently insoluble so as to not be easily removed by leaching but are sufficiently soluble to exhibit toxicity to primary organisms primarily responsible for the decay of the wood. Exemplary particles contain for example copper hydroxide, basic copper carbonate, copper carbonate, basic copper sulfates including particularly tribasic copper sulfate, basic copper nitrates, copper oxychlorides, copper borates, basic copper borates, and mixtures thereof. The particles typically have a size distribution in which at least 50% of particles have a diameter smaller than 0.25 μm, 0.2 μm, or 0.15 μm. At least about 20% and even more than 75% of the weight of the particles may be composed of the substantially crystalline copper salt. Wood or a wood product may be impregnated with copper-based particles of the invention.
Abstract translation: 木材防腐剂包括含有一种或多种微溶铜盐的可注射颗粒。 铜基颗粒是足够不溶的，以便通过浸出不容易除去，但足够溶解以对主要负责木材腐烂的原生生物表现出毒性。 示例性颗粒包含例如氢氧化铜，碱式碳酸铜，碳酸铜，碱式硫酸铜，特别是三硫酸铜，碱式硝酸铜，氯氧化铜，铜硼酸盐，碱式硼酸铜及其混合物。 颗粒通常具有尺寸分布，其中至少50％的颗粒具有小于0.25μm，0.2μm或0.15μm的直径。 至少约20％，甚至超过75％的颗粒重量可以由基本上结晶的铜盐组成。 木材或木制品可以用本发明的铜基颗粒浸渍。
